# Ignore DNS servers advertised by networks (e.g. via DHCP).
#
# This makes NetworkManager refuse automatically provided DNS and lets
# systemd-resolved fall back to the configured global resolvers instead.
#
# Individual connections can override this:
# nmcli connection modify <connection> ipv4.ignore-auto-dns no ipv6.ignore-auto-dns no
[connection]
ipv4.ignore-auto-dns=true
ipv6.ignore-auto-dns=true
